Question

A 100 metre long train crosses a telephone pole in 10 seconds. Find the speed of the train.
(a) 36 km/hour
(b) 33 km/hour
(c) 31 km/hour
(d) 37 km/hour

Answer 1

$here \: is \: your \: answer$
$th e \: correct \:answer \: is \: 36kmh$


Let consider that ,

↪the pole as a point, and the length of the train is 100m,

↪And we know that it crosses that pole in 10s.

distance = 100m

time = 10 s

now ,

to find the velocity we can use the formula ,

$velocity = \frac{distance}{time}$

velocity = 100 / 10 = 10 m/s

by converting m/s to km/hr ,

=》 10×18/5 = 36km/h.

$hope \: it \: helps$

Answer 2

$\textbf{\huge{ANSWER:}}$

$\sf{Given:}$

Length of train = 100 m

Time taken to cross the pole = 10 s

$\sf{To\:find:}$

The speed of the train in km/hr

$\sf{Solution:}$

To simplify our calculation, we can first convert the values in km and hr:

100 m = 0.1 km

10 s = $\frac{1}{360}$ hr

Speed = $\frac{Distance}{Time}$

=》 Speed = $\frac{360}{10}$

=》 Speed = 36 km/hr

Hope it Helps!! :)
